Following the investigation in SERVER-99559, it was decided that operations with an Operation FCV will propagate it in the oplog, so application of those oplog entries in secondaries can use observe the same FCV-gated feature flags as the primary did.

This ticket will:

• Create a new field for oplog entries of type VersionContext.
• Store the VersionContext associated to the source operation context in that field.
• Restore that VersionContext over the operation used for oplog application.
